Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
The following describes the technical solution of the present invention and how to solve the above technical problems with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
The following is an explanation of the terms to which the present invention relates:
in the non-activated state: one state of the communication connection between the ue and the network device is between a connection state and an idle state, which is generally after the ue stops communicating with the network device, because the ue has a possibility of continuing the original communication with the network device, the network device side needs to keep the context of the ue and the corresponding AMF and UPF communication connections, so as to quickly reestablish the communication connection. The inactive state typically occurs in 5G or newer communication modes.
Connection state: a state of the communication connection between the user terminal and the network device, when there is data communication between the user terminal and the network device.
In an idle state: the communication connection between the user terminal and the network equipment is in a state that the communication between the user terminal and the network equipment is stopped often exceeds a set value at the moment, and the context and the corresponding communication connection of the user terminal are not reserved on the network equipment side any more, so that the resources are saved, and the management efficiency is improved.
RNA: based on the radio access network and mainly oriented to the notification area in the inactive state, a service is configured for the base station in the network device to the user terminal establishing connection with the base station, when the user terminal is in the range of the cell covered by the base station, the user terminal can receive the data communication transmitted by the base station, and at the moment, the user terminal is in the RNA.
In the prior art, in order to improve the management efficiency of the network device on the ue and facilitate the fast communication of the ue, a third device state, i.e. an inactive state, is set in addition to the conventional connection state and idle state. However, the inactive state of the existing ue is limited to an RNA, and when the ue leaves the RNA, the ue needs to communicate with the network device to determine whether the device state needs to be changed, such as to switch to an idle state or a connected state. In the case where the ue is in a mobile state or a mobile office state, there is a need to frequently communicate with the network device to adjust whether the device state needs to be adjusted, which causes a large signaling load and increases power consumption of the ue.
In order to solve the above problems, the present invention provides a method for managing a ue, which reduces the frequency of communications between a moving ue and a network device by managing the state of the ue based on the active region of the ue rather than RNA, thereby reducing the signaling load and the power consumption of the ue and improving the management efficiency of the network device.
The following explains an application scenario of the present invention:
fig. 1 is an application scenario diagram of a management method for a user terminal according to the present invention. As shown in fig. 1, in the management process of the ue, when the ue 100 meets a set condition, for example, when moving out of a cell corresponding to an RNA, the ue communicates with the network device 110 to determine whether the device state needs to be adjusted, and the network device 110 notifies the ue whether the state needs to be changed according to a preset rule, so as to complete the state management of the ue.
It should be noted that, in the scenario shown in fig. 1, the user terminal and the network device are illustrated as an example, but the present invention is not limited thereto, that is, the number and the position relationship between the user terminal and the network device may be arbitrary.
The following describes in detail a method for managing a user terminal according to the present disclosure with reference to specific embodiments. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 2 is a flowchart of a method for managing a ue according to the present invention. As shown in fig. 2, the method for managing a user terminal provided in this embodiment includes the following steps:
step S201, determining an active area of the user terminal.
The activity area is determined based on the cell range where the daily activity track of the user terminal is located.
Specifically, the active area is a set of multiple cells that the ue has accessed in daily activities, because the ue generally does not move but is in a fixed location, and when the ue moves, the number of the accessed cells is multiple, such as 5, 10 or more.
The number of cells included in the active area may also be different according to the number of cells that the user terminal has accessed. If the daily range of the user is only within 2km, the number of cells accessed by the user terminal is generally within 5, and the number of cells included in the active area does not exceed 5. If the daily range of the user is 20km (as above, a large number of outages are needed during commuting or working), the number of cells accessed by the corresponding user terminal may exceed 50, and the number of cells included in the corresponding active area may reach 20.
Further, the number of cells included in the active area is generally less than or equal to the number of cells accessed by the ue, because some cell ues have only accessed once or twice, or some cell ues have entered the access only at a very early time and have not accessed again later, such cells are generally not considered to belong to the active area.
The cell referred to in the present invention is used to indicate a communication cell, and is a notification area for providing connection by one base station. A cell may contain multiple base stations, such as a large cell containing tens of buildings, or a base station may cover multiple cells, such as a mini-cell with only two or three buildings.
The range included in the notification area RNA based on the radio access network is generally set based on the base station, and is usually determined according to the range of the cell covered by the base station, when the base station includes multiple cells, the RNA includes the cells, and when the base station includes only a single cell, the RNA also covers the range of the cell, or there may be multiple cells corresponding to multiple base stations covered in the RNA. But in general, the coverage of RNA is much smaller than that of the active area.
Furthermore, the user terminal and the network device side respectively store the cell name lists corresponding to the active areas, the active areas corresponding to different terminals are different, the active areas generally take the form of a form, a linked list or an array and the like, the cell name lists related to the active areas are stored in the user terminal or the network device, and whether the user terminal is located in the active areas can be determined by checking the active areas.
Step S202, managing the user terminal according to the activity area.
Because the area connected by the user terminal does not affect the state change of the user terminal when the user terminal is in a connected state and an idle state, the management of the user terminal related by the invention is mainly carried out based on the non-activated state of the user terminal.
In particular, the present invention relates to the management of a user terminal including the entering, leaving and updating of inactive states.
Exemplarily, when the ue meets the condition of entering the inactive state, by determining whether the ue is located in the active region, it may be determined to set the ue to the inactive state or the idle state, and since the inactive state can facilitate the ue to communicate again, and the range of the active region is much larger than the RNA, the probability that the ue can enter the inactive state can be significantly increased; when the user terminal leaves the original access cell, for example, the user terminal is still in the active area, the user terminal can still be kept in the inactive state without communicating with the network equipment and adapting the state of the user terminal; when the communication time between the user terminal and the network equipment exceeds a set value, the state of the user terminal needs to be set to be an idle state, and if the user terminal is still in an active area, the user terminal can be kept in an inactive state.
Therefore, the user terminal is changed according to the active region based on the entry, switching and maintaining of the inactive state, and when the user terminal is active in the active region, the user terminal generally needs no switching and updating of the state, but needs corresponding operation when moving to the active region or outside the RNA range in the prior art. Because the active area is far larger than the coverage area of the RNA, the frequency of state switching or updating of the user terminal can be obviously reduced, so that the communication interaction with the network equipment about the state of the user terminal is reduced, and the power consumption of the user terminal is obviously reduced.
The method for managing the user terminal determines the active area of the user terminal through the cell range where the daily activity track of the user terminal is located, then manages the user terminal according to the active area, so that the state change of the user terminal, such as the update of an inactive state and the switch between the inactive state and other states, is managed based on the active area.
Fig. 3 is a flowchart of a method for managing a ue according to the present invention. The present invention is applied to a user terminal, and as shown in fig. 3, the method for managing a user terminal provided in this embodiment includes the following steps:
step S301, determining the cell access record of the user terminal based on the cell accessed by the user terminal and the access time.
The cell access record is a record list set in the user terminal and used for counting the accessed communication cells, and a cell list corresponding to the acquisition area can be obtained by counting the connection conditions of different cells in the cell access record.
Typically, the cell access record is also kept in the form of a table, a linked list or an array.
Step S302, deleting the cell access record of which the access time saved in the user terminal and the time length of the current time are greater than the set time length.
In some embodiments, the cell access record itself does not process the cell access information recorded therein to ensure the accuracy of the record. When the user terminal needs to update the active area, the user terminal acquires the data in the cell access record or processes the cell access record so as to ensure the correspondence between the generated active area and the information of the cell access record and further ensure the accuracy and reliability of the active area.
Generally, the reference value of the access record of the cell which is not connected before and after the early time is not large, for example, students who have been in school and on the field are very small after a graduation year, and the reference value of the access record of the student who has been in school and on the position of the school before a year is very small, because the user can rarely go back to the school again. Therefore, the records are deleted, the coverage range of the active area can be reduced, the meaningless communication cost is reduced, the coverage accuracy is improved, and the communication with the user terminal based on the active area is convenient and quick.
In some embodiments, the set duration may be determined according to the frequency of the user terminal communications, where the more frequent the user terminal communications are, the shorter the set duration is, so as to reduce the system memory occupied by the cell access record.
In some embodiments, the duration is set to be at least 7 days and at most 60 days to ensure sufficient access records while avoiding excessive occupation of system memory.
Step S303, based on the cell access record, determining the activity area of the user terminal.
In some embodiments, the storage formats of the cell access record and the active area in the user terminal are the same, and both are in one of a form, a linked list or an array, so that the active area can be quickly obtained from the cell access record through data processing.
Further, based on the number of times of occurrence of the cell in the cell access record and each access time, determining the conversion accumulated number of times of accessing the cell by the user terminal, wherein the conversion weight corresponding to the time when the access time is closer to the current time is larger; and obtaining the activity area of the user terminal based on the conversion accumulated times.
For example, the cumulative number of times of conversion for a cell may be the sum of the converted weights for each access, and if the cell a has been accessed 4 times respectively, and the weights corresponding to 4 times are 0.9, 0.8, 0.5, and 0.1 respectively, the cumulative number of times of conversion corresponding to the cell a may be 2.3 times.
In some embodiments, the weights of the records for accessing the cells in the same time period may be set to the same value, such as the connection from the current time T01 to the time T02, and the corresponding connection weights are all k 1.
Illustratively, the cumulative number of times of conversion of the user terminal into the cell A is recorded as L, the sum of the times from T (current time) to T-T01 is L1, the sum of the times from T-T01 to T-T02 is L2, and so on, the sum of the times from T-T (n-1) to T-Tn (set duration corresponding to the cell access record) is ln, the corresponding conversion weights are k1, k2, … … and kn, and k1 ≧ k2 ≧ … … ≧ kn,
then the conversion accumulated times L of the user terminal accessing the cell A satisfy:
L＝k1×l1+k2×l2+……+kn×ln，
therefore, the influence of different times and times of accessing the user terminal to the cell on the connection condition of the user terminal in the cell can be effectively reflected.
Further, the area where the target cell is located is determined to be an activity area of the user terminal, and the target cell is a cell with a corresponding conversion accumulated time greater than an accumulated time threshold value within a set time length.
In some embodiments, when the number of accessed cells is limited or the communication frequency of the user terminal is low, the cells with the converted cumulative number greater than the corresponding cumulative number threshold may be all used as the cells in the active area. If there are only 6 accessed cells, the reduced cumulative number is 8.1, 7.7, 7.5, 3.2, 2.8 and 0.8 respectively, and the cumulative number threshold is 2, then the cells except the cell corresponding to 0.8 times can all be used as the cells corresponding to the active area.
In some embodiments, the cumulative number threshold is issued to the user terminal by the network device, and the network device may determine the value of the cumulative number threshold according to the frequency of the user terminal communications.
Further, the area where the target cell is located is determined to be the activity area of the user terminal, and the target cell is the cells with the preset number sorted according to the corresponding conversion accumulation times in the set time length.
In some embodiments, when the number of accessed cells is large, or the communication frequency of the user terminal is high, or the user terminal is frequently in a moving state, the cells with the previously set number, which is the most accumulated number of times of conversion, may be intercepted as the active area. For example, there are 80 cells included in the cell access list, and in this case, the cells 15 or 20 before the conversion accumulation number may be intercepted as the active areas.
In some embodiments, the set number is issued to the user terminal by the network device, and the network device may determine the value of the set number according to the frequency of the user terminal communication.
In some embodiments, the determination of the active area by the threshold of the cumulative number of times or by the set number is determined by the network device according to the communication frequency of the user terminal, and the user terminal determines the calculation by that method according to the parameter value issued by the network device. If the parameter value sent by the network equipment is the threshold value of the accumulated times, the cell of which the corresponding conversion accumulated times is greater than the threshold value of the accumulated times is intercepted as an active area.
Step S304, the user terminal is in a connection state, and when the inactivity duration of the user terminal reaches a set value, the indication information containing the current area of the user terminal is sent to the network equipment.
The indication information is used for indicating the network device to determine whether the current area belongs to the active area, and the inactive duration is used for indicating the duration from the time when the user terminal last performs data transmission to the current time.
For the user terminal, the management of the user terminal based on the active area is mainly based on that when the user terminal is in different states, the user terminal completes the operation corresponding to the switching state or the updating state by judging whether the current condition meets the operation of setting the state of the user terminal, such as the switching state or the updating state, and communicating with the network equipment.
Specifically, the inactive duration is a timing function configured in the user terminal, and a corresponding set value can be set for the user terminal through the network device as a time limit. When the inactivity duration reaches a set value, the user terminal generally needs to be switched to an inactive state or an idle state, so as to save the processing memory of the network device and reduce the power consumption of the terminal.
Further, the indication information also includes the current status of the ue, such as a cell id or cell information currently accessed by the ue, and a status record or an operation record of the cell to which the ue has switched connection or when the inactivity duration of the ue reaches a set value.
In some embodiments, the indication information further includes identification information of the ue, such as whether the ue has a function of Discontinuous Reception (DRX) to determine whether an inactive state is enabled or not, whether a mode in which the ue Only initiates Connection (MICO) requires and a currently configured setting value of an inactive timing limit, so that the network device determines whether the ue is set to an inactive state or an idle state.
Step S305, if the first feedback information from the network device is received, setting the user terminal in an inactive state.
The first feedback information is sent by the network equipment when determining that the current area belongs to the active area, and the first feedback information is used for indicating that the user terminal is set to be in the inactive state.
In some embodiments, whether the ue is set to the inactive state is determined by the network device according to a preset rule. When the network equipment determines that the user terminal meets the condition of being set to the inactive state, the network equipment sends first feedback information to the user terminal.
In some embodiments, whether to set the ue in the inactive state is mainly based on whether the ue supports the inactive state, for example, if the ue is an old-fashioned mobile phone, it is likely that a function supporting the inactive state is not configured, and at this time, the ue cannot be set in the inactive state.
In some embodiments, the first feedback message further comprises information configuring various settings for the user terminal, such as the aforementioned time limit setting value of the inactivity timing function.
Step S306, if the current area does not belong to the active area, setting the ue in an idle state in response to receiving the second feedback information from the network device.
And the second feedback information is used for indicating that the user terminal is set to be in an idle state.
In some embodiments, when the ue does not support the inactive state, the network device sets the ue to an idle state even if a cell currently accessed by the ue belongs to an active area.
Step S307, the user terminal is in an inactive state, and receives the paging message from the network device.
Wherein the paging message is sent by the network device in the active area.
In some embodiments, when the network device receives downlink data that needs to be sent to the user terminal, for example, real-time chat data that other user terminals send to the target user terminal, the network device is required to send a paging message through the base station in an active area, when the target user terminal receives the paging message, a feedback message is transmitted to the base station, and after the network device determines a cell to which the target user terminal is accessed according to the feedback message of the target user terminal, the network device sends corresponding downlink data to the user terminal based on the base station corresponding to the cell, thereby completing information transmission.
Step S308, when the user terminal determines that the active area needs to be updated, or when the user terminal needs to be updated in an inactive state, or when the cell to which the user terminal is switched does not belong to the active area, the active area of the user terminal is re-determined.
Specifically, after the user terminal enters the connection state and the corresponding active area establishes the set duration, or when the user terminal is switched to a cell outside the active area, or when the state duration of the user terminal reaches the set duration that needs to be updated, the cell name list in the active area needs to be updated.
When the user terminal is in an idle state and the user terminal accesses to a cell outside the active area, the active area is not updated.
In some embodiments, when the inactive state of the ue passes through the first set duration and the active area is established to pass through the second set duration, the active area needs to be updated, and the first set duration and the second set duration are respectively configured by the network device.
In some embodiments, the time length of the inactive state and the time length of the active area are timed separately by two timing programs respectively configured in the user terminal without interfering with each other.
In some embodiments, the time length of the inactive state and the time length of the active area are timed, and a corresponding timing program corresponding to the ue is also provided in the network device, so as to calibrate the timing result in the ue.
Step S309, sending the activity area redetermined by the user terminal to the network device.
In some embodiments, the network device sends a new active area, and further includes an update time of the active area, so that the network device and the user terminal synchronize the new active area to ensure effective management of the state of the user terminal.
Step S310, the updating time length of the active area and the updating time length of the inactive state of the user terminal are counted again.
In some embodiments, the time limit of the inactive update duration is greater than the time limit of the active area update duration, and the higher the frequency of communications of the user terminal, the shorter these two time limits.
In some embodiments, the corresponding time limits of the active area update duration and the inactive state update duration are both issued by the network device.
In some embodiments, when the ue in the inactive state changes the accessed cell and the reselected cell is outside the active area, an exit inactive state request is sent to the network device, and the network device releases the communication connection associated with the ue and serving AMF and UPF.
The invention provides a user terminal management method, which determines the cell access record of the user terminal based on the cell accessed by the user terminal and the access time, and determines the active area of the user terminal based on the cell access record, thereby managing the user terminal, including the state change management and the active area management when the user terminal is in a connected state and a non-activated state, because the user terminal only moves in the active area, the user terminal does not need to frequently communicate with the network equipment for updating the state, and the active area can effectively reflect the condition of different accessed cells in the daily active track of the user terminal, even if the active area is far larger than the cell corresponding to pure RNA, the quick communication with the user terminal can be effectively ensured, thereby realizing the effective management of the state of the user terminal, and remarkably reducing the state updating communication caused by the movement of the user terminal, therefore, the power consumption of the user terminal is reduced, and the management efficiency of the network equipment on the state management of the user terminal can be improved.
Fig. 4 is a flowchart of a method for managing a ue according to the present invention. The present invention is applied to a network device, and as shown in fig. 4, the method for managing a user terminal provided in this embodiment includes the following steps:
step S401, determining the activity area of the user terminal.
The activity area is determined based on the cell range where the daily activity track of the user terminal is located.
The activity area corresponding to the user terminal is sent to the network equipment by the user terminal and stored, and the network equipment checks the received identification code of the user terminal with the stored user terminal information corresponding to the activity area to determine the activity area corresponding to the user terminal.
Step S402, responding to the received indication information sent by the user terminal, and determining that the current area of the user terminal belongs to the activity area corresponding to the user terminal.
The indication information includes indication information of a current area of the user terminal, and the indication information is used for indicating the network device to determine whether the current area belongs to an active area.
In some embodiments, the indication information sent by the ue includes a current state of the ue, so that the network device determines whether to directly determine an active area to which the ue belongs or to perform other operations, such as adjusting the state of the ue in advance, based on the current state.
In some embodiments, the indication information sent by the ue only includes the status of the ue, and the network device is configured with a rule to determine whether the network device is in the active area when detecting the information including the current status of the ue. Therefore, the user terminal only needs to upload the basic state information, and the network equipment can automatically judge whether the state of the user terminal needs to be managed or not according to the state information, so that the information amount of communication transmission is saved, and the communication efficiency is improved.
Further, the network device compares and judges the current state of the user contained in the indication information sent by the user terminal with the corresponding condition in the set rule, so that the operation to be executed can be determined.
And step S403, sending the first feedback information to the user terminal.
The first feedback information is used for indicating that the user terminal is set to be in an inactive state.
When the network device judges that the condition for setting the user terminal to be in the inactive state is met based on the preset existing rule or strategy, the network device can send corresponding first feedback information to the user terminal.
Step S404, responding to the received indication information sent by the user terminal, and determining that the current area of the user terminal does not belong to the activity area corresponding to the user terminal.
The indication information includes indication information of a current area of the user terminal, and the indication information is used for indicating the network device to determine whether the current area belongs to an active area.
Specifically, it is determined whether the cell accessed by the user terminal is one of the list of cells corresponding to the active area, and only the identification code of the currently accessed cell sent by the user terminal needs to be checked with the identification code of the list of cells corresponding to the active area.
And step S405, sending second feedback information to the user terminal.
And the second feedback information is used for indicating that the user terminal is set to be in an idle state.
In some embodiments, when it is determined that the ue itself does not support the inactive state according to the indication information sent by the ue, the network device also sends second feedback information to the ue.
Step S406, when the user terminal is in the inactive state and downlink data needs to be sent to the user terminal, sending a paging message based on the active area.
Specifically, the network device sends the paging message through all base stations or cells located in the active area at the same time, so as to establish contact with the user terminal at the fastest speed.
When the network equipment receives the feedback information of the user terminal, the paging message is stopped, and the direct data communication is carried out with the user terminal.
Step S407, when the feedback of the user terminal is not received within the set time length after the paging message is sent, the paging message is sent in the tracking area corresponding to the user terminal.
In some embodiments, the network device configures a set duration of the paging message corresponding to the ue, and when the network device still does not receive the feedback of the ue after the set duration, the network device sends the paging message in the tracking area corresponding to the ue. The tracking area is an area range in the prior art and does not need to be set additionally.
Step S408, receiving the activity area sent by the user terminal.
The received active area is replaced by the existing active area and stored, so that the effect of updating the active area record synchronously with the user terminal is achieved.
The method for managing the user terminal comprises the steps that network equipment receives an active area sent by the user terminal, manages the state of the user terminal according to the active area, and comprises the steps of determining whether the user terminal belongs to the active area or not based on indication information of the user terminal, sending corresponding feedback information to the user terminal so as to set the user terminal to be in an inactive state or an idle state, sending paging information to the user terminal based on the active area when the user terminal is in the inactive state so as to send downlink data to the user terminal, and updating records according to the active area uploaded by the user terminal. Therefore, the state used for the terminal can be managed based on the current state information and the activity area information of the user terminal, the implementation requirement of the user terminal can be met, the movable range of the user terminal is larger based on the activity area management, the management action required by the network equipment is reduced frequently, and the processing efficiency of the network equipment is improved.
